How to weld repair cast aluminium

Check out my exact process for weld repairing cast aluminium, in this case, an engine mount.

This is a job for Alternating Current (AC) TIG welding.

Let me show you how I prepare the crack, weld it, and finish it so the repair is almost invisible ;)

  2. 4043 filler rods (or ask your supplier for something suitable)
